This invention relates to.;the manufacture of candle holders orthe like. 1 A common form of candle holder consists of a wirehelix or other form having a stem and coated with a composition of icing or the like applied thereto in the form of a rosebud or other flower. The icing or confection is applied to the form While in moist' Q plasticcondition and sets or hardens lnto ad strong homogeneousmass of the desired con figuration.

An object of this invention isto provide an automatic machine and process for apply.- ing plastic material to :a 1 form to produce candle holders of the type above referred to.

' The'invention contemplates alsuitable carrier oroonveyor on which the forms are mounted and moved to and fromone or more nozzles. As the forms arepresented to the nozzles, moist plastic material is squirted, on

to the forms in the'desired shape. The forms with the ornamental bodies are then moved away fromthe nozzlesand dried.

ribbon of. plastic material is squirted from afnozzle and is applied to the form ivhile the latter isrotated. The machine comprises means for controlling the feeding of the ribbon from the nozzle, the rotation of the formandthe movement ofthe nozzle to'lay the ribbon on theform; to produce the desired configuration. The machine also comprises automatic means for him ing forms into position to have the ribbon applied thereto and for removing the same after the applicationof the plastic material has been completed. The. various motions of the different parts are effected throughcams and other mechanical devices, I the construction and operation of Whichvvill later be described indetailq V r I In one" form of machine a chain conveyor is employed which carries the completed holders thru drier to expedite hardening. 7

Other objects, novel features and advantages of this invention Will be apparentfrom the following specification andaccompanye ing drawings, wherein p l i Fig. 1 is a sideview of a machine embodying one form of the invention;

The driver 13Yis driven from" the main shaft 15 through suitable spiral gears 16 and 16a. Rotationof the driver 13 effects step by step rotation of the table v,11 in the well-known manner of-Genevawheels.

.Thetable 11. is polygonal and is provided along each edge with a plurality setor group of spindles 17 which arerotatably supported .by the table. Oneof-these spindles 17 of each groupis provided with pinions 18 and 19of different diameters. Each spindle 17 carries a gear 20 and idler gears 22.,are carried by 1 the plate 11, each idler gear being in mesh longitudinal slot'. through-which extends a vertical shaft 28 rotatably supported by the I frame 10. A cam 29 is carried bythe'shaft 28 and is engaged by a roller 30 carriedby the link 27. A spring 31having one end attached to the frameand the other'end attached-to the plate maintainsthefollower in contact with the cam 29. j The plate 25 carries a V 29 is of such design that the plate 25 is main pistons 40 and 38.

' series of plungers 32 (see Fig.6) which extend into bearings 830m and bores 33a in a head 33 supported by the frame 10. The cam tained in retracted position during a short portion of the rotation of the cam and during the remaining portion of the. cams rotation the late is caused once to move forward and V I p provided with a roller 67 which engages the back. e In the head 33 there is provided a passage 34 which extends across the bores 33aJThe ends of the passagej34 communicate through conduits 35 (see Fig. 4) with reservoirs 36 provided, with removable covers 37. f In each reservoir 36there is provided a. piston 38, which isconnected-by a rod39 with" a piston 40 inan air cylinder 41.. A sprin'g'42isinterposed between each piston 40 and the end of the corresponding; cylinder 41, this spring tending to oppose upwardmovement of the main shaft 15.-

rota'tion and reciprocation.

slide valve 43 is movable across the bores 33a to' open and close the same. This valve is connected by a link44'with the-free end of a lever 45 pivotally mounted on a stud 46 supported by the frame (see Fig. 2).

V which ehgages the peripheryof a cam 48 mounted on and 7) arranged in cylindrical valve chamb ers formed in extensions 33', each chamber beingfin communication with one bore 33a. Each'valve member 56 is. provided with a passage in one end'of which is threaded a nozzle57-a'nd the other end of which communicates with an elongatedrecess 58 in a surface of the valveImemb er. The nozzle. QTBXEQHClS through a 'slot 59in the wallof thevalvejchamber thereby permitting both Each valve member 56 is capableof both rotary and linear aYial movement in its chamber. .The axes of-the members 56. are inclined upwardly towardjthe table 11. (see Fig. 1) and toward the right (see Fig. 2) so that thenozzles 57 are inclined downwardly toward the table and to the left (see Figsgl and 6). The valve members are provided with extensions 60 provided with arms 60a which are connected by: swivels 61- with racks 62 slidably supported by a standard '63 projecting from the upper part of the frame 10. The outlet of each nozzle is shaped to produce a ribbon of the desiredcrosssection. l

" Links. 64 connect the-free ends of the arms 60a ancla linl: 65 connects one of the arms 60a witho'ne end of a lever 66 which is .p'ivotally supported by the frame intermediate its ends. The other end of theleverfl66is periphery of a cam 68 carried by the shaft 6.9 rotatably supported by the frame 10. A spring70. maintains the follower 67 in engagement with the cam 68. Oscillation of the valve members 56 causes the ends of the nozzles to swing toward and away from the studs 17 along-an inclined'path. Oscillation nozzles 57 at the left end of the slot 59,- after which- ,they are turnedto locate the nozzles at the right end of the slots and then slowly returned'to an intermediate position where they are held temporarily and-are then returned to the original position. When the members 56 are in their extreme upward positionthe nozzles are closed off fromthe con duds-33o.

A'plurality of stub shafts ,72 are rotatably mounted in 'thcstandard 63 andqeachistub pull rod is connected atone end with the free end of; a lever 741rotatably supported by/the stub shaft 46 and having aroller 7 which engages the periphery of a cam 76 carried by the shaft 49., A spring 76a is provided for maintaining the follower 7 5 inengagcnient with the cam 7 6. I p

Beciprocation of the-rod 7 3a efiects oscillation of the pinions 72a andconsequent reciprocation of the racks 62 and valve members 56. The cam 76 is so designed that at one position the lever 74 is held in position to locate the. valve members 56 nearly at the bottom'of their. strokes. As the cam rotates from this position, thelever 74 moves to bring of times between'theirhighest positions and 7 their lowest positions. After the final lifting to the upper positions. the valve members are gradually returned to the original intermediate positions.

it The shaft 49 carries a bevel gear 77 which meshes with a bevel gear 7 8 carried by a'shaft 79 rotatably supported by the framelO. The shaft 79 carries a spiral gear 30which meshes with aspiral-gear 81 carried by the shaft28. The shaft 7 9-also carries abevel gear 83 which meshes witha bevel gear 84 carriedby the shaft69.- Q 1.1

- :A pair of segmental gears 85. and 86 of difierent diameters are mounted on the shaft 87 rotatably supported by the frame 10, these gears being adapted to mesh with the pinions 18. and 19 respectively. The shaft 87 also carries a sprocket wheel 88 around which is trained a chain89 which'is also trained;

- The basesof the cylinders 41 are connected" by pipes 105 with. a supplyiof compressed air and three-way, valves :1-06 are? provided for controlling the admission of air to the cylins ders: ,;;When;the valves cutoff the air supply they also} open thecylinders to the atmos phere. In-eachconduit35 there isprovided a: valve 107 which controls communication between the reservoirs 36 and the passage 34.

Each stub shaft is of the-upper end of the lever 45.

7 common operating rod 108 having a handle 109. The arrangement is such that operation ofa handle 109 either opens or closes both of the valves to which the ro'd108 is connected.

The :operation of the machine is as follows:

Ass nine that the various elements arein the positions. which they occupy at the beginning of a cycle, these positions being those shown in the drawings. The reservoirs 36,'passage 34 and horse 33a are filled with. freely flowing, se f-hardening, homogeneous, plastic material,"such as icing and the pistons 40are pushed upwardly by air in the cylinders, thus causing the pistons 38 to exert pressure on the plasticmaterial Fig. 4). The slide valve 43 is closed, the valve members 56 are near the bottom of their paths and the nozzles 57 are at the right ends of the slots 59 and their ends are acent the forms A (Fig. 2). The plate 25 is in its retracted position (Fig. 3). l/Vire forms A are mountedon the studs 17a of'the row of spindles directly in front of the head 33 (Figs. 1' and 3). The roller 14 just leaving a slot 125 and the driver 13 locks the Geneva wheel 12 againstrotation '3). The, gear is just ready to engagethe pinion 18. (Fig; 5). y

The cycleof operation is as follows: The cam 29 rotates .to permit the spring 31 to draw forward theplate25 and advance the v piun ger's 32 across the passage 34, thereby driving the plungers 32 through the bores 33a. The slide valve43 is then moved by the springf5O to permit fiowof plastic material throughthe nozzles 57 and the plungers 32 are advanced'further and force measured amounts of plastic material through the noz to permit the necessary movement to the left dies 17 are rotated in unison at a relatively high speed by the segmental gear 85 and pin ions 18, 20 and 22, anda. flat ribbon of plastic material is laidspira-lly around the lower end ofthe form A until approximately twofull turns have been made. During this period, the valve members 56 have .been rotated The spinslightlythrough'the medium of the spring 7 7 O, lever 66, link 65 and'arms 60a, this movement being permitted by rotationof the cam 68. The valve members 56 are thus rotated to move the lower ends of the nozzles, 57 .radi ally of the formsA after the first layer of icing has been applied .so that the-nozzles will not stripofl from theforms' the plastic material previously applied: Because of. the inclination of the valve members 56, their rotation causes a slight upwardmovementof the lower ends of the nozzles. This upward-movement is compensated by downward movement of the extensions 60 so-thatthe elevationof the nozzles remains constant. The downward movement of the extensions 60 is effected throughgthe medium of the spring 76a, arm

p 7 3, rod 73a, pinions 72a and racks 62, the rotation of cam 7 6 permitting such movement.

gear 85 moves out of mesh with the pinion 18 and the segmental gear 86 meshes with the pinion 19 and the spindles are driven at a considerably lower speed througha single rotation. The valve members 56, together with the nozzles 57, are now caused to reciprocate by engagement of the follower with the high spots on the cam 76. v V

The ribbon of plastic material is thus laid back and forthin scallop form along the foundation B to form the petals C. After one complete revolution of the spindles, the valve members 56 are held in raised position and are swung to locate the nozzles in the upper ends of the slots 59, thereby shutting off. the nozzles from the bores 33a. At the same time, the plate 25 is retracted and the slide valve 43 closed. Upon the withdrawal of the plungers 32, additional plastic material is forced into the bores 33; and passage 34 fromthe reservoirs 36.. Next, the roller 14 engages another slot 12?) and advances the table 11 to bring another set of spindles in front of the head 33, these spindles previously havingihad forms A mounted thereon. The nozzles 57 are in suchposition that theirends are located above the completed articles and therefore are out of their path of movement. Vhile the table isbeing advanced one step, the valve members 56 arereturned to their original position to locate the ends of the nozzles 5?;adjacent the forms A'and the various other elements assume their starting position for a new cycle. 1

When either of the'reservoirs' 36 becomes empty, the corresponding handle 109 is actuated to close the valves 106 and 107. The cylinder a1 is thereby opened to the atmosphere and the pistons 10, and 38 are returned to their lowposition after which the'cover 37 may be removed and the reservoir 36 filled with fresh plastic material. The handle 109 is then again operated to open the valves 106 and 107. t will be seen that the table serves as a carrier or conveyor fora series'or number of groups of holdersfor the wire forms which are successively moved into cooperative relation to the squirting nozzles.-. The forms and nozzles are intermittently given the necessary relative movements for applying the plastic'material to successive groupsof forms.

The completed candle holders are then removed and allowed to harden before packing. By reason of the factlthat the rotating spindle engages the socket portion of the form instead of the stem it is notnecessary to have the stem coaxial with the socket as it is when the rotative force. is'applied to the The withdrawal of the plungers- 32 isso timed as tostart before the slide valve 43 is actuated to shut off communication'between the bores 33a and the nozzles 57 This cre- After the spindles have been twice rotated and the foundationB laid, the segmental ates a slight suction which draws back into the nozzles any plastic material protruding beyond the end thereof. This prevents the! formation of a drop of plastic material at the end of the nozzle. The valve 43 is closed before communication is established between the outer ends ofbores 33a and passage 34.

The modification disclosed in Figs. 13, 14, 7, and 15 utilizes a chain carrier as a means for supporting the form A. The links of this chain-are connected by means of bushingslll on which are rotatably mounted the rollers 112; In each bushing 111 there is ro- Q tatably mounted a spindle 113 havinga stud 114 for supporting a forinA. Each of the spindles carries a pinion 115 andidler' pinions 116 are provided for causing simultaneous rotation of a group of'six spindles. Every 3? sixth spindle is provided with pinions 117 and 118 which are of proper size tomesh with the segmental gears 85 and 86 such as previouslydescribed, The chain is supported by two sprocket wheels 119 and 120 of which .9 119 is driven by a Geneva movement and 120 is mounted in a dryer 121. Between the sprocket wheels 119 and 120 the chain is supported by guides 122 mounted on brackets 123. Plates are carried by pairs of pindles and overlie the chain to prevent dirt falling into the chain. I i

The operation of this modification is'simi- 'lar to the operation of the previously described construction. Successive groups of 100 spindles with wire forms supported thereon are brought into co-operative relationship to a set of nozzles and after the plastic material has been applied they are moved along sufficiently to permit another set of wire forms 19. to be brought into operative position. The holders are intermittently advanced. in this manner and the finished product carried throughthe dryer 121. By using the chain type of carrier, any'desired length of time 11. for loading, drying and unloading may be provided. e 4

It is of course understood that various other modifications maybe made in the apparatus above described, without in anyway llfi departing from the spiritof the invention as defined in the appended claims.
